Server sent a subprotocol but none was requested?

Question

Node.js

const WebSocket = require('ws');
const ws = new WebSocket('wss://betting-public-gql.gin.bet/graphql');
 
ws.on('open', () => {
    console.log('open')
});
 
ws.on('message', (data) => {
    console.log(data);
});

And here is the
help error

Answer 1

I understand that it's late, but for those who google this question, I'll still answer.
The constructor call must be made with one more argument - the protocol or their enumeration.
Something like this:
```
new WebSocket('wss://betting-public-gql.gin.bet/graphql', 'graphql-ws');
```
